I realize that this might not be the entirely correct forum to answer my question, but I'm going to try. If someone can direct me somewhere else, that'd be appreciated.
The reader loads my rss feed properly, but only on the first load. If I update that feed (whether adding or deleting items) which was read originally and refresh the page that has the reader, the reader still displays the previously fetched content (without the updates). I've checked the .xml file numerous times and it IS uploading properly and contains the most up-to-date content, the reader is just not displaying it. If I save the updated file as something else and change the link in the reader, it again loads the most up-to-date content and then fails to fetch any newer updates after the initial load.
If anyone has any suggestions to fix a seriously frustrating issue, I'd appreciate it.
